Stoptech BBK st60 vs st40 front or rear for F+R advice

I stand corrected Rich, i did not realize they were different other than rotor thickness. Thanks. I had thought the lines and caliper bracket were a standard size and would accept either caliper.

I don't think you can go wrong with ST40 in the front but, since you plan to buy used, why not just be opportunistic? Buy an ST60 kit if a used set comes up. I wouldn't limit myself to the ST40. In addition there are plenty of 18" wheels that fit the ST60 including the OEM 219/260M 18's. It's not at all hard to find an 18" wheel to fit the larger Stoptechs. 18's that fit the Brembo 380's are harder to source (Brembo calipers require more clearance than Stoptechs).

Lastly, you say you don't plan to run 18" wheels because they are "ugly". I would reconsider that because 18's are a better option for track use. It sounds like the brake purchase is motivated by track performance. I would recommend a dedicated set of track wheels in 18". I hope this helps!

But why not get the ST40s and run 17s and save the money on the BBK, pads, and rotors AND tires? You save about $100 for every set of pads and $200 on every set of NT01s? That's a lot of money over a couple of years.

Man you are cheaper than I am.... and I consider myself cheap! I'm all for running 18's for the best balance in performance and cost but I think going to 17's would start to detract from performance (due to tall sidewall) but I haven't tested that theory.

Why not buy a miata so that you can run 14" wheels and 12" brakes; just think of all of the money you would save!

A ///Miata? I should.

But I detect no difference between the 17s and 18s except my car is heavier with the 17s because my wallet is fatter.

17" might be pushing it, but can't argue with the $ savings

LOL the answer is always miata

You're absolutely right, everyone @ the track who's serious has 18 or smaller.
I may get a set of super light weights with some slicks as I improve ma skillz. So I'm not ruling it out, but I don't have a trailer I can haul wheels (fitting them in the car is a PITA) in and I don't want to deal with getting to the track & swapping out. At least for now, I want to stick with just showing up, driving, going home. BBK with the right pads is plenty for me I think. Also I think I'm going to end up going new. Missed out on the recent used sales and I'm getting a great local deal new, so I'm going to order this week.

Another reason I went for st40 is I think st60 is overkill for me, I'm not going to be reaching the limit of these in 30 minute sessions. I'd rather save even more weight. They're also cheaper up front & over time to replace.

Sorry for the thread revival, but i am considering upgrading to a bbk and this info is important to me, as i just bought a set of 18" oem wheels to be my dedicated track set.. is that part of my quoting correct??? 100% sure??
Do ST60 clear the oem 18" wheels??

BTW thanks guys for such an informative thread.

EDit:
Searching some more i found posts that say that clear and other ones that say they don't.. I saw your set up @bigjae1976 but yours don't count, you have rear wheels on the front!

I saw a thread that says that the trophy fit because they are slightly smaller... so again, not 100% sure of anything... So the question remains:

1. Will regular ST60 fit 18" oem Wheels (260 / 219 more specifically)?

2. If the answer is "yes but you need spacers", are there any risks / downsides involved in tracking a car with spacers??

Thanks guys

I have not personally test fitted OEM 18's on standard Stoptech 380mm ST60 brakes. I have test fit them on Stoptech Trophy 380mm ST60 brakes. They require a 10mm spacer but I would suggest a 12.5mm Turner Motorsports spacer. My understanding (based on the multple threads on BBK clearance with 18" wheels) is that the OEM 18's also clear the standard ST60.

Properly installed spacers are not risky or dangerous. You need extended lug bolts or studs to match the spacers you use. I suggest switching to studs. I run Turner Motorsports Studs (90mm or 75mm work with 12.5mm spacer) and 19mm Zinc Coated bolts. Studs are the way to go for track use.

Many thanks for your help

I found in one of the threads that the clearance between 219 and 260 is not the same (to make things even more complicated... )

I've got the 260M.. which most of you don't have since they are the european version.. .

Ok so with this info on my hands, might be a good idea to start looking for sets... One last questions, are the trophy really worth the extra money? Is just some weight saving and a different finish, right? There is a full kit on sale at the moment, but the fact that has no warranty puts me off, and after reading some threads about bbk and brakes i don't know if i am better buying some ST40 for the front since there seems to be a general consensus that they are good enough for track use and significantly cheaper to run.. looks are not a priority.. but those trophy do look good to be honest.

If i were to bite the bullet and buy those used trophies, what problems might i encounter in a second hand set??

Decisions decisions...

I had trophies for a few years and 15k miles, and a hand full of track days. I never had any issues and recently sold them. My concerns about a used set of brakes would be - 1 piston dust boots (make sure not damaged), 2 cosmetic scratches, 3 life remaining in rotors and pads.

I wouldn't hesitate to buy a used set of brakes with plenty of life remaining on them and the price is right.... or the price is reduced sufficiently to reflect the need for new pads and rotors.

I think trophies look a ton better. I can't say whether you would notice the performance difference.

FWIW - my test fitment with trophies was based on 260M wheels (my 2013 came with 260M's). There may be a euro version of the 260M that has different clearance characteristics...

I got the STR40's because they're lighter and I liked the finish better than the paint options on the ST40. Also because racecar, the more R's the better
